Terminals Of Ecu [10/2014 - 10/2015]

NOTE:
  • After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work (Refer to PRECAUTION [10/2014 - ] ).
  • Turn the power switch off before measuring the resistances between CAN main bus lines and between CAN branch lines.
  • Turn the power switch off before inspecting CAN bus lines for a ground short.
  • Before measuring the resistance of the CAN bus, turn the power switch off and leave the vehicle for 1 minute or more without operating the key, switches or opening or closing the doors. After that, disconnect the cable from the negative (-) auxiliary battery terminal and leave the vehicle for 1 minute or more before measuring the resistance.
  • This section describes the standard values for all CAN related components.

HINT: 

  1. NO. 1 CAN JUNCTION CONNECTOR 
    1. Check the No. 1 CAN junction connector.

      HINT: 

      Connectors that connect to the CAN junction connector can be distinguished by the color of their CAN bus lines. When the connectors have been disconnected from the CAN junction connector, reconnecting the connectors to non-original positions on the CAN junction connector does not affect system performance. However, it is preferred to reconnect the connectors to their original positions to avoid negative effects on the wiring such as tension on the wire harnesses, and to make future maintenance easier.
